During ionisation, a (poly)peptide acquires a net positive or negative charge by gaining or losing protons. Besides charging, the ionisation process must ensure that ions are available in the gas phase for the mass analyser. This may seem trivial, but efficient ionisation of nonvolatile ...
Noun1.rest mass- (physics) the mass of a body as measured when the body is at rest relative to an observer, an inherent property of the body mass- the property of a body that causes it to have weight in a gravitational field
The tin isotope 100Sn is of singular interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers—a feature that enhances the contribution of the short-range proton–neutron pairing interact...

63Cu nucleus has 29 protons and also has (63 – 29) 34neutrons. The mass of a proton is1.00728 u,and a neutron is1.00867 u. The combined mass is: 29 protons x (1.00728 u/proton) + 34 neutrons x (1.00867 u/neutron) =63.50590 u ...
X-ray bursts are among the brightest stellar objects frequently observed in the sky by space-based telescopes. A type-I X-ray burst is understood as a violent thermonuclear explosion on the surface of a neutron star, accreting matter from a companion sta
